    Quality control is very important for any good pcb assembly company. Always check if they have certifications like ISO 9001, UL, and IATF. These show the pcb assembly manufacturer follows strong rules and meets world standards. For example, ISO 9001 means the company uses the same quality steps every time.

This means they can make prototypes, small batches, and big orders. LTPCBA uses automatic systems and new technology to make sure every project is done well.
